5. Calculate the molar solubility of \( \mathrm{La}\left(\mathrm{IO}_{3}\right)_{3}(\mathrm{~s}) \) in pure water. \[ \mathrm{La}\left(\mathrm{IO}_{3}\right)_{3}(\mathrm{~s}) \rightleftarrows \mathrm{La}^{+3}(\mathrm{aq})+3 \mathrm{IO}_{3}^{-}(\mathrm{aq}) \quad \mathrm{K}_{\mathrm{sp}}=7.50 \times 10^{-12} \]

\( + P _ { 6 } + PbO _ { 2 } + H _ { 2 } SO _ { 4 } \rightarrow PbSO _ { 4 } + H _ { 2 } O \)
